crypto/x509/pkix: Name.String() rfc2253 AttributeTypes

What version of Go are you using (go version)?

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

What did you do?

Print the issuer (or subject) dn from an x509 certificate:

cert.Issuer.String()

According to https://tools.ietf.org/html/rfc2253#section-2.3 we have this table of

                    String  X.500 AttributeType
                    ------------------------------
                    CN      commonName
                    L       localityName
                    ST      stateOrProvinceName
                    O       organizationName
                    OU      organizationalUnitName
                    C       countryName
                    STREET  streetAddress
                    DC      domainComponent
                    UID     userid

But currently in crypto/x509/pkix we have this

var attributeTypeNames = map[string]string{
	"2.5.4.6":  "C",
	"2.5.4.10": "O",
	"2.5.4.11": "OU",
	"2.5.4.3":  "CN",
	"2.5.4.5":  "SERIALNUMBER",
	"2.5.4.7":  "L",
	"2.5.4.8":  "ST",
	"2.5.4.9":  "STREET",
	"2.5.4.17": "POSTALCODE",
}

Could you please add "DC" and "UID" ? Or maybe could we have special method to pass additional attributeTypeNames for custom converting x509name to the string.

What did you expect to see?

CN=TEST-DESK,DC=test-ca,DC=acm,DC=us

What did you see instead?

CN=TEST-DESK,0.9.2342.19200300.100.1.25=#1307746573742d6361,0.9.2342.19200300.100.1.25=#130361636d,0.9.2342.19200300.100.1.25=#13027573
